I have the ball Wilson evolution. Today, I specially looked at the letters, numbers and symbols on my ball. Compared with yours, I think you bought a fake. You bought 700, and the price in official website is 699. You can buy it at around 550 per double eleven. I bought it for more than 200 yuan, which is basically fake. I also compared your first photo with official website's. The numbers in the second line below the gas nozzle, "0.49" and "0.63", "0" and "4,9" are a little far apart. "My ball is closer to the official website Club and looks more harmonious. I don't know if you often play ball. This 700 is the top ball, the most advanced ball in professional competition, and it feels very good. If your ball feels like hitting the ball, it's basically fake.
